Abstract: Bei dem Runden von Blechzuschnitten traten im Rundapparat (2) bislang Probleme auf, weil die Vorderkante der gerundeten Blechzuschnitte am Ende (48) eines Schlitzes (24) zwischen einer Innenschale (20) und einer Außenschale (22) gegen einen feststehenden Anschlag prallte, so daß der Blechzuschnitt zurücksprang und für den Weitertransport keine definierte Ausgangslage hatte. Zur Beseitigung dieses Problems ist der Anschlag als schwenkbewegliche Dämpfungsklappe (50) ausgebildet, an der ein Fanghaken (54) angeformt ist, welcher den Schlitz (24) an dessen Ende (48) abschließt. Zwischen der Dämpfungsklappe (50) und der Innenschale (20) sind Druckfedern (70) angeordnet. Unter dem Stoß des Blechzuschnittes weicht der Fanghaken (54) zurück und drückt die Dämpfungsklappe (50) um die Drehachse (52) mit ihrem vorderen Teil (50') in den Schlitz (24), wodurch der Blechzuschnitt an der Außenschale (22) vorübergehend festgeklemmt wird. Anschließend wird die Dämpfungsklappe (50) über die Druckfedern (70) zurückgestellt, und die gerundeten Blechzuschnitte können somit aus einer definierten Position von Transportkettennocken (42, 44) übernommen und weitertransportiert werden.
Patent EP-0297359-A2 (EP)
Title: Flexible shaft coupling, especially for control rods of automotive vehicle gear boxes
Inventor: RENK ROLF DIPL-ING FH
IPC: F16D3/50
Filed: 1988-06-16
Abstract: In a flexible hinged connection of two shafts, particularly for the gear change rods of motor vehicle transmissions, the mutually facing shaft ends are connected to one another by a strip-shaped transmission member. The strip-shaped transmission member (32, 32a to 32h) is designed to be rectangular/flat sided in the assembled state and (in the unstressed state) is arranged orthogonally, or essentially orthogonally, with respect to the shaft axis (33, 34) between the two shaft ends (28, 29). The one shaft end (28) engages on one end of the strip and the other shaft end (29) engages on the other, opposite strip end such that the strip-shaped transmission member (32, 32a to 32h) is used exclusively, or virtually exclusively, for torque transmission between the two shafts. Such a flexible hinged connection is simple and space-saving in its construction, and can be produced cost-effectively. In addition, it ensures a high level of stiffness in the rotation direction with sufficient flexibility in the axial direction at the same time. Furthermore, structurally it allows the transmission of axial forces. In addition, the essential advantages of the hinged joint under discussion consist of only a low weight with a virtually unlimited wear resistance and hence a long life, and the capability to damp noise and vibrations and, furthermore, no lubrication being required and a defined play in the axial direction being made possible. <IMAGE>
Patent EP-0304037-A2 (EP)
Inventor: KRAPPEL ALFRED
IPC: F02P13/00
Filed: 1988-08-17
Abstract: On an ignition system for combustion engines with an ignition coil, a high tension lead and a spark plug together with a capacitor arranged parallel to the spark gap, the said capacitor is produced by design modification, particularly of the high tension lead in the cylinder head. For this purpose the high tension lead is designed as a hollow body which is provided on its outside with an insulation element. The insulation element in turn runs inside the bore usually provided in the combustion engine, whose cylinder head is at the same potential as the earth electrode of the spark plug. A capacitor of this type is essentially structural in form and by suitable choice of the insulation element material and structural design of the sleeve and the insulation element permits a variation in the capacitance of the capacitor within wide limits. It is thereby possible to achieve the desired increase in energy in the spark head of the ignition spark in the desired way and without modifying the spark plug.

Abstract: A guiding machine for torches (12), in particular for plasma cutting torches, with at least one torch set (10) on which a torch (12), mounted so as to be adjustable in inclination relative to the vertical, is arranged in a torch holder (11), and the torch is connected to supply units (19) via a torch-hose assembly (18). When the torch is set at an angle to the workpiece surface, a torch-hose assembly connecting the torches to supply units must be available in a greater length than in the case of a vertical torch arrangement. This part of the torch-hose assembly, which develops in the form of a loop above the torch holder, puts up a resistance during the adjustment of the torch. This resistance has to be overcome during the torch adjustment. According to the invention, therefore, it is proposed that, during the adjustment of the inclination of the torch, a device (27, 29, 30, 32) detect the relative changes of length of the torch-hose assembly (18) and, as a function of this, produce signals by means of which a drive (24, 25) displacing the torch-hose assembly is controlled. <IMAGE>

Abstract: A pipe cutting tool (10) especially adapted to cut the interior of the in-the-hole (I-T-H) drill pipe (12, 16) to allow subsequent removal of the pipe above the cut. Due to blasting damages, long sections of I-T-H pipe, otherwise in good condition, cannot be removed because the damaged section prevents the removal of the entire drill string. The tool is adapted to receive power from an external source and includes a frame (30), a motor (24) pivotally mounted on the frame, a cutter (26) that is rotated by the motor (24), and an actuator (50 to 56) for pivoting the motor (24) to urge the cutter against the pipe (12) to cut it. The tool (10) can be twisted about the axis (64) of the pipe by rotating a rigid connector (42) to cut the whole circumference (66) of the pipe.

Abstract: A device for coupling a rotary member (12) to an axially movable input stem (18) of a linear displacement transducer comprises an axially movable element (21) which is coupled to the stem (18) and threadedly engages the rotary member (12). The axially movable element (21) is restrained against rotation by spring loaded detents (26,28) and has abutments (34,35) which can engage a lug (33) on the member (12) when the element (21) reaches its limiting axial positions. This engagement causes the element (21) to be rotated with the member (12) and input to the transducer is arrested.

Abstract: In forming images a photosensitive material is image-wise exposed to heat while being simultaneously exposed to non-infrared actinic radiation. The material includes a support and a layer of microcapsules containing an image-forming agent and a radiation curable composition on the surface of said support. The radiation curable composition is liquid at ambient temperatures and is substantially unhardened in the areas in which the material is simultaneously exposed to heat and radiation and is substantially hardened in the areas in which the material is not simultaneously exposed to heat and radiation. The microcapsules are subjected to a uniform rupturing force such that they image-wise release the image-forming agent.

Abstract: The removal of stains from fabrics is difficult because of the different chemical composition of staining substances, which extends from plant juices to coloured pastes, for example ballpoint paste. To date, stain removers suited to the particular staining substance have been employed both domestically and in commercial cleaning. Since the customary stain removers contain volatile, often flammable solvents, a possibility for long action times, which in conjunction with water brings about reliable washing out of the coloured pigments, has been achieved by treatment with stain removing components which do not contain volatile solvents.
